EcoStruxure Transformer Expert (ETE) Solution
Transformers are widely used in most factories. If not continuously monitored, analyzed, and forecasted, especially for transformers that have been operating for many years, many potential risks can cause serious damage to the business’s operations.
Transformer failures can cause property loss and affect the lives of operating staff due to fire, power outages, delaying operations, and incurring high costs for new transformers and system reconstruction equipment.
Transformer monitoring, analysis, and forecasting solutions help increase stability in business operations and minimize risks for businesses.
Smart solution for transformers – EcoStruxure Transformer Expert (ETE)
The EcoStruxure Transformer Expert (ETE) solution from Schneider Electric is a system for monitoring, analyzing, and forecasting oil transformers.
Specifically, the solution will provide useful insights to help users manage transformer risks, minimize equipment and system downtime, and ensure the overall safety of the operating environment. In addition, through the ETE system, Schneider Electric experts will provide guidance, recommendations, and advice on transformer operation and management.
EcoStruxure Transformer Expert is the stepping stone for businesses to move from passive maintenance to proactive condition-based maintenance (CBM).
Condition-based maintenance (CBM)
EcoStruxure Transformer Expert, Schneider Electric, and the user conduct continuous monitoring to analyze the collected data and make recommendations on appropriate maintenance schedules for the monitored equipment. These recommendations will be provided with detailed information and reports in real-time by the ETE system.
The reporting is conducted continuously as described in the ETE data sheet. Recommendations are made based on historical data and forecasts provided by ETE to help determine the environmental conditions and usability of monitored equipment.
In addition, the ETE system can identify any monitored equipment that is approaching the “end of life” stage, helping to prioritize future maintenance and replacement decisions. As a result, businesses can balance their operating (OpEx) and capital (CapEx) budgets to maximize the economic benefits of the equipment.
EcoStruxure Transformer Expert implementing process
Transformer monitoring and risk assessment process
- Oil sampling and testing
- Installation of sensors for continuous, online data recording
- Automatic analysis and assessment of transformer health and life
- Schneider Electric experts will provide recommendations and advice on risk mitigation for transformers
Outstanding features of the ETE solution:
- Monitoring of transformer operating status and trends referenced against allowable safety limits.
- Transformer life prediction based on insulation aging with load current and humidity values.
- Short-term and long-term risk assessment with recommendations based on standards to take action before an incident occurs in an oil-based transformer.
- Identify optimal conditions to maximize transformer utilization throughout the product life.
IoT Monitoring Technology and 24/7 Online Transformer Health Diagnostics:
- Modern technology accurately monitors transformer health with parameters: water content in oil, temperature, vibration, sound, and RF interference to detect partial discharge
- Intelligent overview interface with self-configuring alerts
- Easy installation in just 45 minutes with fully automated communication configuration
- Lifetime replacement warranty and software upgrade
- Automatic online analysis: temperature, water content in paper
- Partial discharge analysis and transformer vibration trends
- DP (Polymer Decomposition/Polymer Decomposition) predicts lifetime of transformers.
- IEEE, IEC, Rogers, Doernenberg, Duval analysis methods integrated into the online software, allowing analysis of annual oil sample inspection reports
Ensure business information security:
- Storage as unreadable data – Data is stored as “unreadable” encrypted with AES 256 during data transmission. All communication settings are automatic
- Using the AWS (Amazon Web Services) cloud platform, thus the ability to store sensor data for up to 5 years.
- API (Application Programming Interface) security
Benefits when choosing EcoStruxure Transformer Expert (ETE) solutions for businesses
1. Evaluate, monitor, and predict the insulation condition and life of transformers 24/7
Transformer lifetime monitoring and analysis dashboard
Predict the “end of life” stage of the transformer based on the aging rate of the insulation layer with current load and humidity.
2. Short-term and long-term risk analysis
Analysis, Diagnosis, and Evaluation Dashboard to provide maintenance plans
Develop life extension plans through data sent from the engineering department and maintenance plans based on actual transformer condition.
3. Support in making quick and effective decisions
Transformer Analysis and Evaluation Dashboard
Support businesses to optimize decisions based on automatic data collection, analysis and online recommendations by industry standards.
4. Optimize transformer system management
Transformer moisture monitoring and analysis dashboard
Check the health status of each transformer to determine the maximum condition. From there, businesses can optimize performance throughout the life of the transformer with the support of intelligent scenario simulation tools.
5. Prolong transformer lifetime
Transformer Monitoring Dashboard
Through the EcoStruxure Transformer Expert dashboard, customers will have an overview of the real status of the transformer and receive warnings as soon as the transformer shows unusual changes.
As a result, the life of the transformer can be extended by many years because risks have been promptly handled before serious damage occurs.
